I have been looking at iPad apps for usability issues for the past few weeks. Here is a quick list of the good, the bad, and the ugly.
The good: IMDB, Scifi Wire, Adobe Touch
The bad: The buggy WordPress app
The Ugly: AP News
About the iPad itself, very slick, very cool/fun to use. On the down side, no SD slot, no USB, and Apple’s “walled garden.”
